Rockies 10, Athletics 4

His role with the Rockies still unsettled, Smith was impressive over five innings Friday as Colorado beat the Oakland Athletics 10-4.

Smith gave up three hits and a run while striking out six and walking one. He could end up starting in Triple-A Colorado Springs or coming out of the bullpen because closer Huston Street will start the season on the disabled list because of right shoulder inflammation.

Randy Flores, the other left-hander in the bullpen, is a specialist who rarely pitches a full inning. He was hit with a line drive on the left forearm Wednesday and is waiting for the swelling and soreness to subside.

Flores is expected to start the regular season, but ideally the Rockies would like to have a second left-hander, one capable of pitching multiple innings, to go with Flores and help get the game to Morales.

In four games this spring, Smith has a 1.93 ERA, allowing 12 hits and three runs in 14 innings with six walks and 14 strikeouts.

The Rockies broke a 1-all tie with a three-run sixth that included a two-run double by Melvin Mora, who scored on a two-out double by Jordan Pacheco.

Smith, who pitched 190 1/3 innings for the A's as a rookie in 2008, was acquired in November '08 along with Street and outfielder Carlos Gonzalez for outfielder Matt Holliday. An assortment of ailments limited Smith to 49 1/3 innings last year.

He added about 15 pounds over the winter with a protein-rich diet and at 201 pounds said he "feels more durable on the mound than I ever have."

Smith picked Gabe Gross off first base in the second, his third pickoff of the spring.

Smith said no one has spoken with him about the possibility of relieving at the outset of this season.

"My next step is workout tomorrow as a starter," Smith said. "I'm not going to change any game plans and start speculating, 'What if?' until they come to me and say, 'This is what we need you to do."

A's starter Trevor Cahill allowed five hits and one run in five innings, throwing 68 pitches -- 45 strikes -- in his longest outing of the spring.

"I felt a lot better the third, fourth and fifth inning," Cahill said, "which is good because I'm just getting my strength up."
